The headmistress at a girls prep school...

The headmistress at a girls' prep school in the old South (circa 1959) calls down to the army base and speaks with one of the officers: "We're having a social here at school and I was wondering if you could send some of your nice young men to attend." "Why of course," the Lieutenant answers. "Just one thing," says the lady. "Of course you'll make sure there aren't any Jews there." "Why of course," the Lieutenant answers. On the day of the dance, a bus pulls up from the base. Out comes a platoon of black GIs. The schoolmistress is quite distressed. "Why, why, there must be some mistake," she says to a burly black Master Sergeant. "Why heck no, ma'am," he replies. "Lt. Goldberg NEVER makes a mistake!"
